Ellen E Jones and Mark Kermode take a deep dive into the cinematic subconscious to explore dreams in film and television.

Mark talks to Sandra Hebron, psychotherapist and head of screen arts at the National Film and Television School, about the origins and history of dreams in film.

He also speaks to director Bernard Rose, best known for his 1992 film, Candyman. They discuss his debut film, Paperhouse, and how it portrays the blurred lines between reality and dreams.

Taking a look at everything from The Sopranos to The Big Lebowski, Ellen investigates some of film and TV's most memorable dream sequences with help from film critic, Anne Billson.

Ellen then speaks to independent film director, Tom DeCillo, whose 1995 film, Living in Oblivion sought to subvert the clichés of the cinematic dream sequence.
